Gold stamping paste and preparation method and application thereof

Abstract

The invention relates to gold stamping paste. The gold stamping paste is prepared from, by weight, 50-75 parts of waterborne acrylic emulsion, 5-30 parts of acrylic modified rosin emulsion and 0.3-2 parts of a thickening agent. The paste can be used for gold stamping and printing of fabrics at a normal temperature, and quick fabric processing can be realized only by providing of a flat operating plane, a pressure about 30N and normal-temperature curing time about 5min. The paste reaches 5.1N/mm in peel strength between fabrics and gold stamping paper, and washing fastness of the fabrics subjected to gold stamping and printing reaches level five. Components of the gold stamping paste are optimized and are simple, easy to obtain and low in cost. By adoption of the gold stamping paste, people's conception of high energy consumption, long process time, complexity in operation, product infirmness, harmfulness to environment and the like of a traditional gold stamping process can be changed,productivity level can be remarkably raised, and the gold stamping paste is suitable for large-scale popularization and utilization.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a paste for bronzing and its preparation method and application. Background technique [0002] Bronzing paste is a special paste specially used for fabric bronzing. The bronzing paste is attached to the surface of the fabric after screen printing. It can transfer the bronzing foil to the textile through the transfer printing machine. The fabric can be printed with various The bright color with unique style and style is relatively fashionable, but there are also some problems, such as low washing fastness, low softness, easy discoloration under high temperature pressing, and patterns that are easy to deform and have lace after high temperature pressing. The requirements for bronzing effects are getting higher and higher, and these problems are becoming more and more prominent. Therefore, bronzing printing workers urgently need to solve these problems. At present, the bronzing ...

[0002] Bronzing paste is a special paste specially used for fabric bronzing. The bronzing paste is attached to the surface of the fabric after screen printing. It can transfer the bronzing foil to the textile through the transfer printing machine. The fabric can be printed with various The bright color with unique style and style is relatively fashionable, but there are also some problems, such as low washing fastness, low softness, easy discoloration under high temperature pressing, and patterns that are easy to deform and have lace after high temperature pressing. The requirements for bronzing effects are getting higher and higher, and these problems are becoming more and more prominent. Therefore, bronzing printing workers urgently need to solve these problems. At present, the bronzing paste on the market is mainly high-temperature bronzing paste, and the pressing temperature is generally 100-150°C. prone to the above defects

[0003] At present, all the hot stamping pastes on the market have defects to a certain extent. For example, CN102718921A discloses an adhesive emulsion for environmentally friendly textile hot stamping printing pastes and a preparation method thereof. The emulsion consists of the following components in weight percentage: Composition: 0.5%-3% emulsifier, 30%-50% soft monomer, 6%-15% hard monomer, 2%-5% functional monomer, 0.1%-0.3% initiator, 40% deionized water %~60%, neutralizer 0.5%~2%, the advantage of the obtained emulsion is that hot stamp
